MIS604, Semester 2: Requirement Engineering Report on Handyman App

This Software Requirement Specification (SRS) document details the requirements for the 'Your Handyman' app, developed for ABC Pty Ltd. The report outlines the app's purpose, scope, and overall description, including product perspective, user classes, operating environment, constraints, and assumptions. System features are illustrated using UML diagrams, such as use case diagrams, swimlane diagrams, state-transition diagrams, and dialog maps. Data requirements are defined through logical data models and data dictionaries. The document also covers external interface requirements, including user, software, and hardware interfaces, along with quality attributes like usability, performance, and security. References are also included. The app aims to connect customers with tradespersons for job postings and execution, providing a platform with features like user accounts, search functionality, instant messaging, and a booking system.

MIS604 REQUIREMENT ENGINEERING
1. Introduction
1.1 Purpose
The implementation of the innovative technologies is being done in the major
businesses for improving the methods by which the products as well as the services are
provided to the customers and the clients. This Software Requirement Specification
document has been developed for providing the complete overview of the “Your handyman”
app for the ABC Pty Ltd that would provide the customers and the tradesperson with the
effective platform for posting jobs and executing jobs respectively. This software requirement
specification document provides the clear description of the how the application would work
and the working of the application has been illustrated using the UML diagrams and the user
interfaces.
1.2 Document conventions
As development team is mainly responsible for this SRS document, no kind of
ambiguity arises from the usage. There is extensive distinction, moreover, among the
utilisation of the words “Customer” and the “Tradesperson”. The customer is interacting with
the application for posting any job requirements and browsing through the profile of any
registered tradesperson and then contact with the tradesperson using the instant messaging
facility in the application (Ali et al., 2018). The tradespersons are interacting with the
interface for registering themselves and then browsing through the various job available and
then make the contact with the customers using the in-app instant messenger. This document
would be printed on proper A4 paper in the Times New Roman font. The normal size of the
text used in this document would be 12 black, and the headings would be 13 size in the Times
New Roman font.

1.3 Project Scope
The project of the “Your handyman” app would be initiated after proper planning has
been completed. Initially, the team would properly analyse the tasks and then deliver the
minimal needed project management documentation, the estimates as well as the list of
various risks as well as the milestone chart. The “Your handyman” app version 2.0 would be
rolled out after conducting the analysis of any bugs found in the initial version of this app.
For the Apple issues, the workaround would be probable for implementation with the
reasonable amount of the efforts as well as the risks. The main constraints of this project is
that there might a slight chance that the QA workload on various other products might affect
the schedule of the “Your handyman” app. The additional requests for the update to the
website of the ABC Pty Ltd might extensively influence the schedule of “Your handyman”
app.
2. Overall description
2.1 Product perspective
It is the web based system that would implement the client-server model where the
clients would be allowed to interact with the server of the organisation and gain important
data from the servers. The “Your handyman” app provides the simple mechanism for the
users and the tradesperson to interact with each other and provide various services along with
payments (Osman & Zaharin, 2018).
The following could be considered as the major features that would be included in the
“Your handyman” app:
 Cross platform assistance: Provides the required operating support for majority of
the known as well as the commercial operating systems

4
MIS604 REQUIREMENT ENGINEERING
 User account: The system permits the users with creating their respective accounts
in this system and then provides the main features of easily updating as well as
viewing the profiles of the tradespersons (Sabriye et al., 2017).
 Number of users supported at one time: Even though number of the users that are
using the system could not be determined precisely but it could be considered that
the system would possess the ability of supporting significantly large number of
the online users at one time.
 Search: The search is implemented for the users to find the tradesperson and the
search function would be directly linked with the tradesperson database. The
search function would return the list of neighbouring list of the tradesperson who
are available (Beck, 2017).
 Instant messaging: It would provide the users with the effective platform for
conducting discussion among the customers and the tradesperson and book the
tradesperson upon satisfaction.
 Booking system: Permits the users in submitting their request of any kind of job
that is available and wait for acceptance of the job by any of the skilled registered
tradesperson.
 FAQs section: The Frequently Asked Section in the application would contain all
the answer to the problems that are frequently posted on any handyman app.
2.2 User classes and characteristics
The users of the application would be the adults and the senior citizens of the both the
gender who would need any handyman for the jobs in their homes. It is considered that the
users would have the fundamental knowledge of properly using the application and would
gain the access to the application by registering themselves using the correct details (Park,
2019). The administrator of the application is predicted to the extensively familiar with

5
MIS604 REQUIREMENT ENGINEERING
proper working of the interface of tech support system. The administrator would possess the
ability of updating the database of the application and manage all the information of the
customers and tradespersons.
2.3 Operating environment
The “Your handyman” app that is being developed for ABC Pty Ltd. would be the
web based system and would need the operating environment for the client as well as the
server GUI. The application would be properly operating in the Android and the iOS
operating systems. The 128 bit SSL encryption environment would be enabled in the
application for allowing the secured transactions with the PCI-DSS compliance (Sanyal &
Ghoshal, 2018). The specifications that have been considered for the software, the technology
and the hardware are:
 Capability of providing services when connected over WiFi or any mobile
network
 Capability of allowing data access of any secured network
 Keypad and touchscreen are provided for using according to the convenience to
the users
 Processor providing over 500 MHz speed (Vaish & Sharma, 2018)
 Consistent supply of power
 Can use the microphone, the camera and the gallery
 Users can provide the input in the forms
2.4 Design and implementation constraints
Create the account in the application by entering the personal details such as the
name, address, phone, email along with the option of saving the payment card details
 In any situation where network is not accessible:

6
MIS604 REQUIREMENT ENGINEERING
o If the application is not able to exchange the data over network, the
application would provide the notification "Connection not available"
 In situation when the application is not able to access the services of the
mobile hardware:
o For example, the camera is not working for taking pictures, the
application would provide the notification “Cannot access camera”
 Lock account
o If the user has failed following the policies of the application
o In the situation where there is spamming by over 8 users
o Maintain the consecutive marked spam center
o Increment the spam centre (Sabriye & Zainon, 2018)
o Deactivate any account when the spam number has reached over 5
2.5 Assumptions and dependencies
 Power supply
 Data and the network availability
 Improved connection for efficiently exchanging the data over any network
 Availability of the mobile services (Hassan & Hassan, 2016)
